Description

Planet is a private earth imaging company who provides daily global coverage of the earth at high spatial resolution. Daily images are composted into a weekly basemap based on image quality. Data is collected using a constellation of over 150 individual satellites called doves. Currently, three generations of doves are used in this dataset: Dove-Classic, Dove-R, and SuperDove. Planet data is available using surface reflectance.

Normalized Difference Vegetation Index (NDVI) provides information on vegetation growth and productivity. Effects due to climate, weather, fire, water, and vegetation and crop management practices can be assessed through developing and visualizing maps, time series, and anomalies of NDVI.

NDVI is calculated as the normalized difference between the red and near infrared (NIR) bands following the equation (NIR – Red) / (NIR + Red) (Huete et al., 1985; Jackson and Huete, 1991). Red light is absorbed by chlorophyll while NIR light is reflected by plant mesophyll tissues. NDVI ranges between -1 and 1 where values above 0.5 represent conditions of high vegetation vigor.

Bands Used:
Red: 0.590-0.670 μm
Near Infrared (NIR): 0.780-0.860 μm
